Annotation Type PropagateNull
Signals that the annotated property signals the presence of the mapped type: reflective mappers should map a null bean if this property is null, rather than a present bean with a null property value. This is useful e.g. for a
LEFT OUTER JOINor an optionally-present compound value type.
